Abstract

A method of manufacturing a disc-shaped device for storing and dispensing perfume which has a plurality of compartments for storing different perfumes by molding a unitary piece of plastics material to form at least one wall of a compartment, resilient bands, a sealing stem flange and an actuating stem.

Description

The present invention relates to a device for storing and dispensing liquid, such as perfume, according to the preamble of claim 1 and of a method of making a device according to the preamble of claim 9.
Samples of perfume may be distributed with magazines so that the purchaser of the magazine may be tempted to buy the perfume after trying the sample. One example of a known perfume sample is a ScentSeai® which comprises a pouch in which the perfume is sealed between two layers of foil laminate and is released when the pouch is opened. Alternatively, another known perfume sample is a SoentStrip® in which the perfume is micro-encapsulated between two layers of paper and is released by snapping apart the two layers. A problem with these perfume samples is that the perfume can only be sampled once at the time it is initially released and it cannot be tried again later. Also, a user may have some difficulty in releasing perfume from the perfume sample when, say, tearing open the pouch.
DE 2129 597 discloses a device having the technical features of the preamble of claim 1, more precisely a container for storing and dispensing detergent. This document also discloses a method of making a device for storing and dispensing liquids according to the preamble of claim 9. The container has a hollow stopper at one end and the stopper has an opening to the container and an outlet. The stopper contains a valve which blocks the outlet and the valve seals the stopper outlet by having a diaphragm spring engaging the inside of the stopper and urging a flange of the value against a seat comprising the inside of the stopper adjacent the rim of the outlet. The diaphragm spring of the valve has ports and the valve also has a shank which extends from the stopper. To dispense detergent, the shank is pushed into the stopper compressing the diaphragm spring and moving the valve flange away from the seat. The stopper outlet is thus unsealed and detergent flows out of the container via the stopper opening, the spring ports and the stopper outlet.
An object of the present invention is to provide a device for storing and dispensing liquid, such as perfume, which alleviates at least one of the above-mentioned problems.
According to one aspect of the present invention there is provided a device for storing and dispensing liquid, such as perfume, comprising a compartment for storing the liquid, said compartment having an aperture through which liquid is released from the compartment; sealing means for closing the aperture; resilient means mounted within the compartment and being arranged to bias the sealing means to close the aperture; and actuating means connected within the compartment to said resilient means and extending out of said compartment through said aperture, said actuating means being arranged upon actuation thereof to open said aperture against the bias of said resilient means and thereby enable liquid to be released from said compartment, characterized in that
said device comprises a plurality of said compartments, each of said plurality of compartments respectively having a said aperture, a said sealing means, a said resilient means and a said actuating means and being intended to contain a different liquid.
The resilient means enables the compartment to be resealed after liquid has been released by the actuating means, thereby enabling any liquid still in the compartment to be retained and released subsequently.
The sealing means may comprise a seal formed with the compartment wall in which the aperture is formed. The actuating means may comprise an elongate member extending through the aperture and on which the sealing means is mounted, such that actuation of the elongate member opens the aperture by moving the seal away from the compartment wall.
The sealing means may be at least provided by an interference fit between the actuating means and the aperture through which the actuating means extends. The actuating means may comprise an elongate member having at least two different cross-sectional areas along its length, a first cross-sectional area providing the interference fit to seal the aperture and a second cross-sectional area being smaller than the aperture, such that movement of the elongate member within the aperture releases the interference fit and opens the aperture.
The device may comprise a moulded unitary piece of plastics material forming at least one wall of each compartment, the sealing means, the resilient means and the actuating means.
The compartments may be arranged in an annular formation with each of the apertures being formed in an outer peripheral wall of the device.
There may be a movable shield provided over each aperture so as to inhibit accidental actuation of the actuating means.
According to another aspect of the present invention there is provided a method of making a device for storing and dispensing liquid, such as perfume, said device comprising at least one compartment for storing the liquid, the or each compartment having an aperture through which liquid is released from the compartment;
sealing means for closing the or each aperture;
resilient means mounted within the or each compartment and being arranged to bias the sealing means to close the aperture; and
actuating means connected within the or each compartment to said resilient means and extending out of said compartment through said aperture, said actuating means being arranged upon actuation thereof to open said aperture against the bias of said resilient means and thereby enable liquid to be released from said compartment, the method characterized by the step of
moulding a unitary piece of plastics material to form at least one wall of the or each compartment, the resilient means, the sealing means and the actuating means.
By moulding a unitary piece of plastics material comprising at least one wall of the or each compartment, the resilient means, the sealing means and the actuating means, the device is inexpensive to make. The device is cheap enough to manufacture to enable it to be given away with a magazine, and is preferably arranged to have dimensions to enable it to be inserted into the magazine or be attached to the front cover of the magazine. The device is designed to last for a relatively short period and be disposed of when finished with.
In moulding the device, the resilient means is formed in an uncompressed state. The step of moulding the unitary piece of plastics material may include providing integrally interconnected said actuating means and said resilient means by an integral hinge with the actuating means being moulded at an angle relative to the resilient means, and the actuating means is subsequently pivoted in line with the resilient means so that the actuating means can extend through the aperture.
By moulding the actuating means at an angle relative to the pivot means, the actuating means can be made without any seams along its length as it is able to be cast in a surrounding mould and not between two mould faces. Thus, where the sealing means is provided by an interference fit between the actuating means and the aperture through which the actuating means extends, by not having any seams to obstruct the interference fit, the interference fit is improved.
The method may comprise the steps of breaking the resilient means from the wall or walls of the compartment to which it is moulded, and moving the resilient means and actuating means integral therewith towards the aperture so that the actuating means extends through the aperture. The step of moving the resilient means and actuating means integral therewith may include compressing the resilient means so that the resilient means biases the sealing means to close the aperture. The or each compartment is preferably formed with retaining means for retaining the resilient means when broken from the wall or walls.
The resilient means may be compressed to allow the actuating means to be pivoted in line with the resilient means so that the actuating means can extend through the aperture. Where a spacing between the end of the resilient means nearest to the sealing means and the part of the sealing means for forming the seal with the compartment wall in which said aperture is formed is greater than a spacing between the end of the resilient means, when unbiased, nearest to the sealing means and the compartment wall, this enables the resilient means to bias the sealing means to close the aperture.
The resilient means may be moulded with at least one of the side walls of said compartment. Additionally, further steps may comprise attaching top and bottom walls to the device to seal the at least one compartment with liquid contained therein.

Referring to Figure 1 of the accompanying drawings, a device 1 for storing and dispensing a plurality of different perfumes, scents, fragrances or olfactory aromas, comprises a disc-shaped perfume holder 2 with apertures 3 spaced along the peripheral annular wall 4 of the holder 2 and an actuating elongate member or stem 5 protruding through each aperture 3. The disc-shaped holder 2 with its stems 5 fits within a shield 6 which has a circular base 7 and a peripheral annular wall 8. The annular shield wall 8 has a gap 9 through which a single stem 5 of the holder 2 can be accessed and the gap 9 extends as an indentation or recess into the shield base 7.
Referring to Figure 2, the disc-shaped perfume holder 2 has a wheel-shaped member 10 having a plurality of compartments 11,11' arranged in an annular formation. The wheel-shaped member 10 has an outer peripheral wall which is the annular peripheral wall 4 of the holder 2 and an inner annular peripheral wall 12 with side walls 13 extending radially between the two peripheral walls 4,12 to define the sides of the compartments 11,11'. The inner peripheral wall 12 defines the edge of a base from which a, preferably cylindrical, hub 14 protrudes, the hub 14 being centrally positioned within the inner peripheral wall 12. First and second circular walls 15,16 or covers cover the top and bottom of the wheel-shaped member 10 and the first circular cover 15 has a central hole 17 whose edge is coincident with the inside face of the inner peripheral wall 12.
Referring to Figures 3 and 4, the outer peripheral wall 4 has an inside face within each compartment 11. The inside surface forms a planar face 18 extending from infills 32 with rounded corners in the corners between the outer peripheral wall 4 and side walls 13 for all but one of the compartments of the wheel-shaped member 10 and these compartments 11 each have a pair of stop members 19. Each stop member 19 extends from an opposite side wall 13 of the compartment 11 and is inclined towards the outer peripheral wall 4. Each stop member 19 is preferably of the same height as the side wall 13. Each of the compartments 11 with stop members 19 also has one of the apertures 3 in the outer peripheral wall 4. A base portion 20 has a pair of flanges 33 abutting against the stop members 19. The base portion 20 is shorter in height than the side walls 13 of the compartment 11 and a column portion 34 extends from the middle of the side of the base portion 20 facing the inner peripheral wall 12 and the column portion 34 is the height of the side walls 13. A pair of resilient bands 21 bending away from each other extends from the base portion 20 to a base portion 22 for the elongate stem 5. The stem base portion 22 abuts the planar face 18 to form a seal with the face 18 of the outer peripheral wall 4 of the compartment 11 and the stem 5 extends through the aperture 3 from the stem base portion 22. The elongate stem 5 is stepped having a portion 23 with a larger diameter or cross-sectional area adjacent the stem base portion 22 tapering to a portion 24 with a smaller diameter or cross-sectional area and the distal end 25 of the stem 5 is rounded. Each aperture 3 forms an interference fit seal with the larger diameter stem portion 23.
Referring to Figure 5, the shield 6 has a window 35 in its base 7 adjacent the gap 9 and has a, preferably cylindrical, hub 27 extending from the shield base 7. The hub 27 fits between the hub 14 and the inner peripheral wall 12 of the wheel-shaped member of the disc-shaped perfume holder 2 so as to form the device 1 shown in Figure 1 and to enable the holder 2 and shield 6 to rotate relative to each other.
In a preferred embodiment, the device 1 has a diameter of approximately 80 millimetres and a thickness of approximately 6 millimetres.
In use, each compartment 11 of the disc-shaped perfume holder 2 having an aperture 3 in its outer peripheral wall 4 can contain a different perfume. The first cover 15 of the holder 2 can identify each compartment 11 containing a perfume by the part of the cover over each such compartment 11 being marked by a different number 36 or by other identification means such as a different colour.
To release a perfume stored in a compartment 11, the user rotates the disc-shaped perfume holder 2 about the shield 6 until the elongate stem 5 for the compartment 11 marked by the chosen identification mark 36 appears in the shield window 35 (see Figure 8). The user actuates release of perfume by pushing the actuating elongate stem 5 (indicated by arrow 28 in Figure 3) into the compartment 11 causing the resilient bands 21 to be compressed against their bias. This causes the stem base portion 22 to move away from the planar face 18 so as to break the seal and the larger diameter stem portion 23 to move into the compartment 11 so that the smaller diameter stem portion 24 is within the aperture 3, thereby breaking the interference fit seal (see Figures 6 and 13). This opens the aperture 3 and releases perfume from the compartment 11. As the base portion 20 is shorter than the side walls 13 of the compartment 11, perfume from either side of the base portion 20 can be released. When the user releases the stem 5, the bias of the resilient bands 21 causes the stem base portion 22 to reform the seal with the planar face 18 and the larger diameter stem portion 23 to reform the interference fit seal with the aperture 3.
A website address may be printed on the centre of the second cover 16 and the device 1 is marked by a colour or other identification means such as a number. The user accesses the website on a computer and identifies the device 1 she has by entering the device identification means. A list of perfumes contained in the compartments 11 of that device 1 are then displayed along with the compartment identification means 36 identifying which compartment contains which perfume. From this, the user knows which compartment 11 in the device contains the perfume that she wants to try.
When the device 1 is not in use, the compartment 11' which does not have an aperture in its outer peripheral wall 4, is aligned with the gap 9 in the shield wall 8 as illustrated in Figure 7 so as to inhibit accidental actuation of any elongate stem 5. The outer peripheral wall of the compartment 11' has a curved indent 37 to highlight the device 1 being set to a position in which the stems 5 cannot be actuated.
In manufacturing the device 1, the wheel-shaped member 10 is moulded as a unitary piece of plastics material integral with the elongate stepped stems 5, the stem base portions 22, the resilient bands 21 and the base portions 20. Referring to Figures 9 and 10, each base portion 20 is initially attached to the side walls 13 of the compartment 11 by a pair of frangible nubs 29. The stem base portion 22 has a hinged pivotal part 31 from which the stem 5 protrudes. The pivotal part 31 is initially pivoted so that the stem 5 extends downwardly (in Figure 10) relative to the wheel-shaped member 10. This enables the stem 5 to be cast in one surrounding mould and not between two mould faces or halves which would cause a pair of seams to be formed along the length of the stem 5.
After the wheel-shaped member 10 has been moulded the elongate stem 5 is rotated about the hinge of the stem base portion 22 until the pivotal part 31 contacts a face of the part of the stem base portion 22 to which the pivotal part 31 is hinged and cannot rotate any further. This aligns the elongate stepped stem 5 with the aperture 3 in the outer peripheral wall 4 of the wheel-shaped member 10 (see Figure 11). Pressure is applied to the back of the base portion 20 so as to break the base portion 20 from the nubs 29 and push the elongate stem 5 through the aperture 3 until the stem base portion 22 abuts the inner planar face 18 of the outer wall 4 of that compartment 11. The infills 32 can help guide the stem base portion 22 so that the stem 5 enters the aperture 3. The base portion 20 is also pushed past the side wall stop members 19 causing the base portion flanges 33 to deflect the stop members 19 inwardly until they regains their original shape once the flanges 33 have passed (see Figure 12). Having the base portion 20 pushed past the stop members 19 causes the resilient bands 21 to be sufficiently compressed so that the stem base portion 22 is biased against the planar face 18 to form a seal and the flanges 33 abut against the stop members 19.
The second cover 16 is glued or heat sealed to one side of the wheel-shaped member 10 and each compartment 11 is filled with perfume. Compartment 11' which does not have an aperture 3 is left empty. The first cover 15 is glued or heat sealed to the opposite side of the wheel-shaped member 10 so that the perfume is sealed within the disc-shaped perfume holder 2. The attached covers 15,16 are not glued or heat sealed to the resilient bands 21, the stem base portion 22 or stem 5 for each compartment 11 of the wheel-shaped member 10 so that the stems 5 can be actuated. The covers 15,16 may, perhaps, be glued or heat sealed to the base portions 20 and/or to either end of the column portion 34. Each cover 15,16 has a curved notch 38 (see Figure 2) matching the curved indent 37 in the outer peripheral wall 4 so that the covers 15,16 can be correctly aligned, the compartment identification numbers 35 printed on the first cover 15 matching the right compartments 11. The shield 6 is then attached to the holder 2 to form the device 1 as illustrated in Figures 1, 7 and 8.
A second embodiment is illustrated in Figures 14 and 15 and parts of the device 50 which remain unchanged have the same reference numerals as used in describing the first embodiment.
Each stop member 51 extends from an opposite side wall 13 of a compartment 11. A curved portion 52 abuts against the stop members 51 and curves towards the outer peripheral wall 4. A resilient zig-zag portion 53 extends from the curved portion 52 to the stem base portion 54. The pivotal part 55 having the elongate stem 5 is hinged to a channel part 56 of the stem base portion 54 and is of a size to fit between the sides of the channel part 56.
In manufacturing the device 50, the elongate stem 5 is rotated about the hinge of the stem base portion 54 until the pivotal part 55 fits within the channel part 56 and cannot rotate any further. Pressure is applied to the back of the curved portion 52 so as to break the curved portion 52 from nubs 29 on the compartment side walls 13. The curved portion 52 is pushed past the side wall stop members 51 causing the ends of the curved portion 52 to be deflected inwardly until the curved portion 52 regains its original shape once past the stop members 51. Having the curved portion 52 pushed past the stop members 51 causes the resilient zig-zag portion 53 to be sufficiently compressed so that the stem base portion 54 is biased against the planar face 18 of the outer peripheral wall 4 of the compartment 11 to form a seal and the ends of the curved portion 52 abut against the stop members 51.
In a third embodiment illustrated in Figures 16 and 17, the resilient zig-zag portion and the stem base portion of the second embodiment have been modified. Parts of the device 40 which remain unchanged have the same reference numerals as used in describing the second embodiment.
The resilient zig-zag portion 41 extends from a protrusion 42 on the inner peripheral wall 12 of the wheel-shaped member 43 to the stem base portion 44 abutting the planar face 18 of the outer wall 4 (see Figure 17) and no stop members or nubs are required. Also, the pivotal part 45 of the stem base portion 44 extends beyond the channel part 56 of the stem base portion 44.
In manufacturing the device 40, the wheel-shaped member 43 is moulded with the elongate stepped stem 5 pivoted downward relative to the wheel-shaped member 43 (see Figure 16) and the resilient zig-zag portion 41 uncompressed (i.e. unbiased). The resilient zig-zag portion 41 is then sufficiently compressed to enable the elongate stem 5 to be rotated so that it is within the outer peripheral wall 4 and aligned with the aperture 3. Following this, the zig-zag portion 41 is released so that the pivotal part 45 of the stem base portion 44 abuts the planar face 18 and the elongate stepped stem 5 extends through the aperture 3 and forms an interference fit therewith.
The distance or spacing "A" (see Figure 17) between the face of the pivotal part 45 which abuts the planar face 18 and the end of the channel part 56 adjoining the resilient zig-zag portion 41 is greater than the distance or spacing "B" (see Figure 16) between the end of the resilient zig-zag portion 41, when unbiased, adjoining the channel part 56 and the planar face 18 to ensure that the pivotal part 45 is biased against the planar face 18 to form a seal in the finished device 40.
Whilst particular embodiments have been described, it will be understood that various modifications may be made without departing from the scope of the invention. For example, the resilient bands 21 or zig-zag portion 41 may be replaced by other forms of resilient means. The device 1 may not be restricted to a circular shape and may, for example, be rectangular where the shield slides along a rectangular perfume holder. The aperture 3 and/or stem 5 can be formed in any suitable way to form an interference fit such as having the aperture tapered to form a smaller aperture. Furthermore, any number of compartments may be provided, including a single compartment. In manufacturing the device 1, the pivotal part 31 may be initially connected by frangible nubs to the infills 32 of the compartment 4 and these nubs are broken when the elongate stem 5 is rotated.
